This is incorrect. The energy released by burning hydrocarbons is not the same as the energy required to convert carbon dioxide into biomass. The difference is that biomass has lower energy density than hydrocarbons.
The rate at which we burned fuel and the rate at which we undo the damage are not linked. We can remove carbon dioxide either faster or slower as we collectively choose.
Yes, biomass is not coal & oil yet, time and pressure are required for that. We can choose the rate of carbon capture, sure, but storing it faster requires more power and effort. In fact, it is recommended to first try to avoid releasing more CO~2~ where possible.
